sciencehabit writes: A purported conflict between the century-old theory of classical electrodynamics and Einstein's theory of special relativity doesn't exist, a chorus of physicists says. Last April, an electrical engineer claimed that the equation that determines the force exerted on an electrically charged particle by electric and magnetic fields—the Lorentz force law—clashes with relativity, the theory that centers on how observers moving at a constant speed relative to one another will view the same events. To prove it, he concocted a simple "thought experiment" in which the Lorentz force law seemed to lead to a paradox. Now, four physicists independently say that they have resolved the paradox.Link to Original Source
